LF imaging has been researched for more than a century [1]}. In 1908, Lippmann used small and closely spaced circular lenses to record different perspectives of a scene, so that an image could be observed from a selected perspective through an array of lenses [2]}. In 1936, Gershun coined the term light field, referring to the amount of light traveling in all directions through every point in space [3]}. In 1991, Adelson proposed the Plenoptic function P(x,y,z,t,\(\lambda \) ,\(\theta \) ,\(\phi \) ), describing the information carried by light rays at any point in 3D space (x,y,z), for all directions (\(\theta \) ,\(\phi \) ) and wavelengths (\(\lambda \) ), along time (t).
The static 4D LF [4]}, L(x,y,u,v), also known as Lumigraph [5]}, proposed a representation based on the intersection points of the light rays with two parallel planes [6]}.
